IMPROVEMENT 1N Mael-:HNI: Fon JQINTING szrAvns.

` TheSeliedule referred'to in these Letters Patent and making part of the same.

`To all whom fit may concern n '-Be it known that we, LAMARTINE R. FULDA and MARTIN FULDA, both of the city and county of San i have invented a Machine for Working Staves; and we dolierehy declare the followingldescription and accompanyingdrawings are sufficient to enable any person skilled in the art or science to which it most nearly appertains, to make and useoursaid invention or improvements without further invention or experiment.

j l The objectA of our invention `is to construct a machine bythe use of which'the` staves of barrels, tanks, and casks of: all sizes can be given the proper bilge andbevel, either one or bo-th edges at once, and with or without bending; but 4it i'sprincipally useful for very large work, such as the largest wine-casks, in

which the staves are very thick, and cannot be bent and where the work' must be very Our machine consists ofl'two saws, planers, or other cutters, mounted, on carriages, opposite to each other,

. and moving backand forward transversely` to' the mo-V tion of the staveand its carriage. `'lhese cutters stand at an angle to the stave and to each other, this angle being variable, to suit thesize and radius of the cask `to b'e made; and, in moving back or forward, their carriages also move on a corresponding curve, so that the bevel of either wide or narrow staves will lie in radial planes of the proposed cask. The stave-carriagemoveson ways, which descend each' way from thecentre, so that, as the stave passes between the cutters, each end is brought near their upper edges, where -it, is naITow, while the middle passes through .lower down, where they are` further apart, and thus `shapes the stave, while the' angle of the cutters gives the proper bevel. Tapering or tank-staves may be v formed by raising one` end oi' the stave on the carriage, while,`in this case, the `ways are in a horizontal position. l l

`To morev fully explain our invention, reference is madeto theaecompanying drawings, of which--i l Figure l is a vlongitudinal vertical section.

Figure2 is :a transverse section. Figures 3, 4, and 5, are detailed views oi' parts of the machine.

-A A are two side pieces,

` which are fastened firmly together by cross-timbers,

4or to the door, at such a allow the moving of the carriage B between them.

This carriage moves on ways C O, which are attached to the sides A` A, the ways being made in two parts each,` which are pivoted totheside pieces A, at

` orlnear their centre, as at D. Their outer ends are "adjustable up or down by means of bolts IE, moving or other-equivalent device. l

The carriageis moved 1om one end to the other by arack, G, and pinion H; and, in order to keep the two in contact when the ways are inclined, the rack is cut in the middle, or made in two parts, and may be connected together by a rule 'or other joint, which should be formed by two of the teeth, or, at least, so low down as not to materially alter the relative position of the teeth. i'

A guiding-post or bar, l, holds this joint, and slides so that, as lthe carriage moves over the ways at varying distances from the pinion, the weight of the 'rack will'tend to keep it down, and the joint allows it to keep always in gear with the pinion.

Small slots may be cut into the side 'of the guidenearly in position for the particular form of staves that may be at the time in process ot' manufacture, while, at the same time, the rack is allowed a slight motion.

In order to allow the vendsof' the rack snfcient play, they areslotted, as at K, and haveguiding-pins, to attach them to the carriage.

The carriage may move on rollers, which run on the waysor, as inthe arrangement here shown, it may have sliding blocks, L L, pivoted at each end, these giving it greater steadincss -in its movements.

lhe stave to he worked is placedv on the upper part 'of the carriage, with the outside down, and is held `irmly by levers or screws M M, which may be operated in any known manner, for convenience. The bent frame N, through which they pass, isfastened to the ends of the carriage, so that it can be turned from side to side, as will be hereafter explained.

which pass through boxes on a frame, Pf is hinged or pivoted, at one end, to the adjusting-frame or carriage Q. v

By means of screws R R, the cutters and the frame P can be raised and lowered, moving about the hinges S, and thus change `their angle to the staves, according to the size ofthe cask to be made. When this has been determined, the screws may be set tight, and so remain till all the staves of that size have been linished. One of the screws R or depress the frame, and the other to bind it iirml'y at any point. V The adjusting-frames or carriages Q are moved back orvforward, as the stave may be wide or narrow, by a screw, T.

rod,and a` screw, J, set in, so as to hold the r'ac'kv in the slots F, and iixed .at any point desired by nuts v up and down through the lower part of the carriage,

The saws or cutters fO O are mounted on arbors,

This frame Lin each serves toraise In order to make the edges of both wide and narrow staves of any one cask radial planes from the centre of it, the cutters and their carriage Q must move back or forward on an are of a circle whose centre is the centre of the cask to be made; and, for this purpose, patterns V are made for different sizes, and can be fastened to the permanent bed lV. These patterns have their upper surface curved, asV shown, and serve as ways for the carriage Q; and, by'this means,- the edges of the staves are always cut to t exactly.

Figure 6 shows another arrangement ofthe frames P.

The staves may be formed in two ways: rst, by

bending them, and then cutting the edges; and, secondly, in this machine, without bending; and this, in large work, is done with much more facility.

rlhe size of the cask and the difference between the head and bung-diameter being determined, the ways O O are lowered at each end a distance equal to onehalt` this diierence, and patterns V, corresponding to the size of the cask, are placed on the beds lV W. The cuttersare then set, so as to give the right bevel, by raising or depressing the inner end of their carriages by the screws R It. v

After the machine is once arranged, any number of stares for that size of cask can be made, one at a time, or sufficient for as many casks as may be wanted, each stave being placed on the carriage, and held by the screws M Saws, horizontal or vertical planers may bc used, as may be best for dicrent kinds of work.

In large, thick staves, it is better to joint them without bending; but, to dosmall work, or where there is lunch curve, it may be necessary to place blocks under each end of the stave, and I set all the screws tightly, the middle one causing the stave to bend as much as is desired. In this case, the -ways are raised to be nearly or quite. horizontal, and the curve will bring the ends and middle of the stave against the cutters at points which will give it the required shape. In forming tank-staves, the ways are horizontal, and one end of the stave is raised, the other being clamped on the bed, thus giving it a regular taper, the cutters, in every case, making tl1e-bevel.

If the curve of a stave be very great, it may be necessary to.put 'an additional piece on the bed or carriage B, so that the centre will not fall below the arbor of the saw.

Single machines, or those that cut only one side at a time, may be made, by using only one of the cutters, and having the ways V fixed and horizontal, in which case curved patterns or models, aa, iig. 4, must be fastened to the upper part of the carriage, to give the 'proper bevel, and the frame N can be swung to one side, as in fig. 3, so that the screws M M will bear directly on the stave, which will be bent, as before described.

In making tank-staves with this form of the maend of the stave will be higher thanthe other', as before described.

These cleats may simply be placed on the bed of the carriage, when desired, or they may be fastened to a bed permanently.

Similar' patterns, b l), but convex, instead of concave, maybe used in jointing large heads, which are made slightly concave, for strength to resist the internal pressure.

The stares of large. casks are made somewhat thinner in the centre than at the ends, to facilitate D bending. We accomplish this by constructing a bed, c, the upper face of which is made straight, and has a stop, d, at one end, against which the ends ofthe stavcs rest. The lower surface c is curved as much as it is necessary to thin the, staves, and rests upon the bed of the machine; or it may be used equally well upon an ordinary planing-machine. A pin, f, passes through the centre, and keeps the bed in position. As many staves as the width of the bed will admit are laid upon it, and the end passes under the cutters. As the centres of the staves approach the knives, the increased thickness oi'the bed causes the knives to take oli' more of' the wood, and thus give the staves the required thinness at that point.

'lo use the supplementary bed c, it will be necessary to remove the upper portion of the bed4 B, and substitute the ordinary'planing-gear for the cutters.

Having thus described our invention,

What we claim as new,'aud desire to secure by Letters Patent, is-

' l. In combination with the cutters orl saws O, arranged in planes oblique to each other, the device consisting of the adjustable ways G, carriage B, guide I, rack G, and pinion H, for carrying the stave through between the cutters, and, at the same time, raising and depressing it, as required, to give it the proper shape, substantially as described.

2. The arrangement of' the hinged frame P with the screws It, for adjusting the cutters O so as to bevel the edges of the staves, according to the size of the casks to be formed, substantially as described.

3. In combination with the carriages Q, supporting the cutters O, the curved removable ways V, for adjusting the cutters to joint staves of different widths for the same cask, or casks of the same diameter, substantially as described.

In witness whereof, we havehereunto set om hands and seals'.
